As illustrated in FIG. 8, the cigarette injection machine may further include a first position sensor 251, a second position sensor 252, and a cigarette size selector sensor 253.

The first position sensor 251 may be a mechanical switching sensor that senses the position of the cigarette tube loader barrel 225 when the cigarette tube loader barrel 225 moves horizontally to a stop position to fill an empty tobacco tube of a first preset size (e.g., a king size which is 84 mm).

The second position sensor 252 may be a mechanical switching sensor that senses the position of the cigarette tube loader barrel 225 when the cigarette tube loader barrel 225 moves horizontally to a stop position to fill an empty tobacco tube of a second preset size (e.g., 100s size which is 100 mm).

The cigarette size selector sensor 253 may be a mechanical switching sensor that is mounted below the internal cigarettes tubes chamber 221. The cigarette size selector sensor 253 may allow the user to select the first preset size or the second preset size cigarettes (e.g., the King size or 100s size cigarettes).

FIG. 9 illustrates a block diagram of a micro-controller unit (MCU) board mounted in the cigarette injection machine in accordance with embodiments of the present disclosure. The cigarette injection machine may further include an MCU 261 to control all the sensors, motors, and buttons, and LEDs mounted in the cigarette injection machine.

The MCU 261 is connected to a power source 262 to receive direct current power.

The MCU 261 may receive sensing data that indicates the real-time operating status of the cigarette injection machine, from the first mechanical switching sensor 231, the second mechanical switching sensor 233, the first position sensor 251, the second position sensor 252, and the cigarette size selector sensor 253.

The MCU 261 may receive a user input for selecting the number of cigarettes from the first push button 213 or the second push button 214. When the MCU 261 receives a signal from the first push button 213, the MCU 261 may generate an instruction for making a first number count of cigarettes (e.g., 5 cigarettes). On the other hand, when the MCU 261 receives a signal from the second push button 214, the MCU 261 may generate an instruction for making a second number count of cigarettes (e.g., 10 cigarettes). The first LED 213A and the second LED 214A are coupled to or disposed around the first push button 213 and the second push button 214, respectively, to indicate the real-time operational status of making the cigarettes. For example, when the first push button 213 is pressed, the first LED 213A flashes while the cigarette injection machine is making the first number count of cigarettes (e.g., 5 cigarettes). When the second push button is pressed, the second LED 213B flashes while the cigarette injection machine is making the second number count of cigarettes (e.g., 10 cigarettes). The first LED 213A and the second LED 213B are turned off upon the completion of making the cigarettes.

Based on the sensing data from the first mechanical switching sensor 231, the second mechanical switching sensor 233, the first position sensor 251, the second position sensor 252, and the cigarette size selector sensor 253, and also based on the signal from the first push button 213 or the second push button 214, the MCU 261 may control the 180 degrees servo motor 232, the 360 degrees servo motor 234, and the high-torque 360 degrees servo motor 235.

The MCU 261 is implemented in hardware, firmware, or a combination of hardware and software. The MCU 261 is a central processing unit (CPU), a graphics processing unit (GPU), an accelerated processing unit (APU), a microprocessor, a microcontroller, a digital signal processor (DSP), a field-programmable gate array (FPGA), an application-specific integrated circuit (ASIC), or another type of processing component. In some implementations, the MCU 261 includes one or more processors capable of being programmed to perform a function.

The cigarette injection machine may further include a memory 263 that stores computer-readable instructions or software programs executable by the MCU 261 to control the sensors 231, 233, 251, 252, and 253 and the motors 232, 234, and 235 of the cigarette injection machine.

The memory 263 may include a random access memory (RAM), a read only memory (ROM), and/or another type of dynamic or static storage device (e.g., a flash memory, a magnetic memory, and/or an optical memory). The memory 263 may also include a hard disk (e.g., a magnetic disk, an optical disk, a magneto-optic disk, and/or a solid state disk), a compact disc (CD), a digital versatile disc (DVD), a floppy disk, a cartridge, a magnetic tape, and/or another type of non-transitory computer-readable medium, along with a corresponding drive.

FIG. 10 is a flowchart for describing a method of operating the cigarette injection machine in accordance with embodiments of the present disclosure. FIGS. 11A-11L illustrate the operational process of the cigarette injection machine.

With reference to FIG. 10, when the cigarette injection machine is powered on in operation S401, the cigarette injection machine may perform an initialization process in operation S402, including operation S403 of turning on the LEDs 213A and 2136 and operation S404 of testing the motors 232, 234, and 235.

Once the initialization process is completed, the cigarette injection machine enters into a standby mode and waits for a start button (e.g., the firs push button 213 or the second push button 214) to be pressed, in operation S405.

With reference to operation S406 of FIG. 10 and the start process of making cigarettes shown in FIG. 11A, when an empty cigarette tube is placed into the internal cigarettes tubes chamber 221 and fresh tobacco is filled into the internal tobacco chamber 222, the user may push the start button to start making the cigarettes.

With reference to operation S407 in FIG. 10 and the process of loading the empty cigarette tube shown in FIG. 11B, the MCU 261 controls the 180 degrees servo motor 232 to rotate the cigarette tube loader barrel 225 to load the empty cigarette tube.

With reference to operation S408 in FIG. 10 and the process of moving to the feeder nozzle position shown in FIG. 11C, once the empty tube is loaded, the MCU 261 controls the 180 degrees servo motor 232 to rotate the cigarette tube loader barrel 225 to the position of the tobacco feeder nozzle 241, so that the empty cigarette tube is ready to be filled with tobacco.

With reference to operation S409 in FIG. 10 and the process of sliding the cigarette tube loader barrel 225 shown in FIG. 11D, once the empty tube is at the position of the tobacco feeder nozzle 241, the MCU 261 controls the 360 degrees servo motor 234 to slide the cigarette tube loader barrel 225 to a requested size position (e.g., the King size or 100s size position) in the horizontal direction.

The opposite view of FIG. 11D is shown in FIG. 11E to illustrate the first position sensor (e.g., a King size position sensor) 251 and the second position sensor (e.g., 100s size position) 252.

With reference to operation S410 in FIG. 10 and the process of starting the high-torque 360 degrees servo motor 235 shown in FIG. 11F, once the first position sensor (e.g., a King size position sensor) 251 or the second position sensor (e.g., 100s size position) 252 is triggered by detecting the empty cigarette tube at the requested size position (the King size position or the 100s size position), the MCU 261 stops the sliding movement of the cigarette tube loader barrel 225 and starts the high-torque 360 degrees servo motor 235 to drive the tobacco fluffing claws 223 and the tobacco feeder spiral rod 242.

With reference to operation S411 in FIG. 10 and the process of feeding the tobacco through the tobacco feeder spiral rod 242 shown in FIG. 11G, the tobacco feeder spiral rod 242 continues to rotate until a cigarette filled sensor 271 is triggered. The cigarette continues to get filled until the cigarette filled sensor 271 detects the fullness of the tobacco in the cigarette tube.

With reference to operation S412 in FIG. 10, and the process of detecting the filled status shown in FIG. 11H, as the cigarette is being filled, the cigarette tube slides on the fullness of the tobacco. With reference to the process of stopping the high-torque 360 degrees servo motor 235 shown in FIG. 11I, and the process of moving the cigarette tube loader barrel 225 back to the starting position in FIG. 11J, when the cigarette filled sensor is triggered, the MCU 261 stops the high-torque 360 degrees servo motor 235, and controls the 360 degrees servo motor 234 to move the cigarette tube loader barrel 225 back to the starting position.

With reference to operation S413 in FIG. 10 and the process of unloading the filled cigarette in FIGS. 11K and 11L, when the empty cigarette tube is filled with tobacco, the MCU 261 controls the 180 degrees servo motor 232 to rotate the cigarette tube loader barrel 225 to the position of the cigarette holder (e.g., a dispenser tray) 311 and thereby to unload the freshly filled cigarette onto the cigarette holder 311.

In operation S414 of FIG. 10, when the MCU 216 determines that the requested counts of cigarettes are made, the MCU 261 finishes the process of making cigarettes, and otherwise, proceeds to operation S405 until the requested counts of cigarettes are made. For example, when the first push button 213 is pressed in operation S406, the MCU 216 checks whether a first number count of cigarettes (e.g., 5 cigarettes) are made. On the other hand, when the second push button 214 is pressed in operation S406, the MCU 216 checks whether a second number count of cigarettes (e.g., 10 cigarettes) are made.

In accordance with the embodiments of the present disclosure, the automatic cigarette injection machine offers a convenient way of making cigarettes by implementing the machine with a microprocessor running a software which manages and monitors the automation process using sensors, servo motors, and mechanical components.
